SUSSEX ﻿﻿Bishop Serratelli visited St. Monica Church here May 21 and celebrated a vigil Mass marking the Solemnity of the Most Holy Trinity also known as Trinity Sunday. The feast, marked one week after Pentecost, celebrates the Church’s doctrine of the Trinity — three Persons in one God — the Father, the Son and the Holy Spirit. During the Mass, the Bishop also administered the Sacrament of Confirmation to young people of the Sussex County parish.
